Question

Two grams of hydrogen diffuse from a container in 10 minutes. How many grams of oxygen would diffuse through the same container in the same time under similar conditions.

• A. 0.5 g
• B. 4 g
• C. 6 g
• D. 8 g

Answer 1

Answer: (A)

0.5 g

Answer 2

$r _ { H } = \frac { 2 g m } { 10 \mathrm {~min} }$ if $r _ { O } = \frac { x g m } { 10 \mathrm {~min} }$ $r _ { O } = r _ { H } \sqrt { \frac { M _ { H _ { 2 } } } { M _ { O _ { 2 } } } } = \frac { 2 } { 10 } \sqrt { \frac { 2 } { 32 } }$

$\frac { x } { 10 } = \frac { 2 } { 10 \times 4 } = \frac { 1 } { 2 } \mathrm { gm } . = .5 \mathrm { gm }$
